Marita Cheng: When I was growing up,

I had a family friend
who became blind in his 20s.

When we went out as a family,
he would say to me,

"Rita hold my hand, hold my arm,
and tell me what you see."

So I'd say, "There's 
some flowers here to the left.

There's a gate here to the right.

There's a mountain over in the distance."

And he would say,
"What color are those flowers?

Can I use my hand,
reach out, and touch them?

Could you lead my hand to that?"

I'd say, "Oh, they're pink, they're blue."

And he'd say, "Tell me more,
tell me more about what you can see.

Share it with me."

About eight months ago,
Alberto and I decided to create an app

to enable blind people
to recognize their surroundings.

We used something called
convolutional neural networks,

which is a computer system
that's been trained on millions of images.

It learns the features of a dog.
It learns what a flower looks like.

It learns a fork, a knife,
everyday objects.

Using this system,
we created something called "Aipoly"

that recognizes
over 1,000 everyday objects.

So, a blind person just needs
to walk around with their phone,

and put it over various objects,
and it will say the name of the object.

Using voice over, the phone can relay
the word on the screen

to that blind person,

so they know exactly
what's in front of them.

(Applause)

Since we released
our application in January,

we've had over a 100,000 downloads
around the world.

The app has been so popular
we've translated it into seven languages.

Alberto Rizzoli: After experiencing
the technology the first time,

our users kept asking us for more.

We asked them

to think of our technology
as a superpower for a moment,

something they could effortlessly
evoke at any time,

and gain understanding
of what was in front of them.

And surprisingly,

nobody really wants
X-ray vision or telescopic goggles,

but what everyone wants
is more information.

It's not surprising

because 60% of the information
that we perceive comes through sight.

It is the main tool that we use

to understand our surroundings
and often, to make decisions.

If you're blind you must rely
on other senses like touch or hearing,

and you miss out
on the lightning-fast identification

that our brain and eyes do every second
of every day, if you're a sighted person.

We went

to the Santa Clara Valley Blind Center,

and we tried to build this superpower.

We tried to see what kind
of information people wanted,

and it's simple things
like whether a dish is clean or not,

whether you can cross the street,
what product am I looking at?

Things that can lead to a decision,

from a simple gaze, to an understanding
of the situation in front of you.

We asked what form factor
people preferred, and we built it.

So we put together

some jawbone conductive headphones,
a pair of sunglasses, and a tiny camera,

and we asked our friends
to think of a common situation

in which they had to make
many small decisions,

and we told them
we will be giving them the prototype,

and taking them
in the middle of that situation.

Let's see how it went. (Video starts)

[We asked blind individuals

[what are the hardest things to do
when visually impaired]

I mean it takes me forever
to go grocery-shopping.

Even with someone helping me
that has known me for years.

I'll say, "What's in that cabinet?"

Or develop a system,
right to left, top to bottom.

[So we took them grocery shopping
with our technology]

Computer: Oranges.

Man: This is great. I'm really liking it.

Apples, grapes, carrots.

I'm looking, I'm looking.

Computer: Lilies.
Man: Lilies.

Computer: Bouquet.
Man: A bouquet, ahh!

Computer: Roses, flowers.

Man: Can I take these home?

This is great.

Computer: Roses.
Man: Roses.

Computer: Bouquet, tulips.
Man: Tulips.

Computer: Pineapple.
Woman: It's a pineapple.

Computer: Mango.
Woman: Mango.

Computer: M&Ms.
Woman: M&Ms.

Computer: Tic Tac.
Woman: It just said, "Tic Tac."

Computer: Tic Tac.
Woman: Tic Tac.

Computer: Paper note, calendar.

Woman: Calendar, you got it.

Wow, I didn't know what that was at all.

Computer: Pretzels.
Woman: Pretzels.

Computer: Pretzels.
Woman: It said, "Pretzels."

Computer: Lipton tea.
Woman 2: Lipton?

Tea?

Computer: Lipton teabags.

Woman 2: It's like I'm seeing it,
but I'm not, it's seeing it for me.

Computer: Coffee mate.
Woman 2: Mate; coffee mate.

It didn't say "coffee,"
but it kept saying "mate."

Computer: Mate, mate.

Man 2: I put on the glasses,

and right away, it told me
there was an apple, there were oranges,

and there was this, and there was that,
and it's like, "This is great!"

Instant love.

(Applause)

AR: That little pair of glasses
connected to their phones

could identify four
to 5,000 objects in real time.

That's about the capacity
of a five-year-old child.

A simple accessory
can now expand a person's perception

to thousands of new possibilities.

This is the power of marrying
artificial and human intelligence,

and the potential
is still vastly untapped.

This isn't going to be a revolution
just because GPUs are getting faster,

or the research is getting more open,

but because the barriers of entry
to impacting millions of lives

for artificial intelligence
are getting lower and lower.

The Paralympic games
are starting in a few weeks,

an event where sheer force of will,
training, and technology

turn people with a disability
into super humans.

and so, too, will all ability to think,
perceive, make decisions, and learn

increase exponentially.

You will be building
the tools to make this happen.

So tomorrow, with your morning coffee,

take 40 minutes
and try out a tutorial on deep learning.

Build yourself a small superpower.

All it takes is your laptop,
and a bunch of data,

like your holiday pictures.

Superpower engineer -
that's a great dream job.

The good news is that the world
needs many, many more of them

so we can't wait to see
what you will be building next.

Thank you.

(Applause)
